A coalition of over 80 organizations and Internet companies on Tuesday sent a letter to Congress calling for a public investigation into recently revealed National Security Agency surveillance programs. The full letter and list of signatories include the American Civil Liberties Union, the Electronic Frontier Foundation, Mozilla and reddit.

The coalition launched a website to accompany the letter, stopwatching.us, that advocates for congressional disclosure of spying activities. Laura Poitras, the filmmaker who has a byline on the Washington Post story that broke the news of the NSA’s PRISM Internet surveillance program, is highlighted on the website as a private signatory.
